Mobile data connectivity issues when using gmaps

[bigJ334]

I was wondering if someone else has this issue. When I use Google maps in areas with varying data networks my phone seems to lock itself to whatever network it had when I started using Google maps. This affects the whole phone while Google maps is running and using data (eg, searching or guiding thru a route). Once the app is stopped normal connectivity function is restored. This also happens during a phone call using the oneui native phone app.

I experienced this most recently yesterday while using Google maps to guide me to the parking location of my car through a busy town centre. I arrived there using waze which didnt seem to trigger the issue to occur, though this was while driving to the city, a use case for which the issue doesn't occur as reliably when using Google maps.

Hi and Welcome.

I usually download Offline Google Maps for the whole area I normally use.

This helps with areas where there is poor mobile reception.

Not a direct solution but no harm trying

When in Google Maps > Click your profile photo (top right) > offline Maps and zoom in or out depending how much area you want.

Data network as in mobile data

Hey, thanks. Yeah I usually do the same but the issue occurs regardless. In my experience Google maps wont use offline maps unless there is no network connectivity at all. Also, if i try to search for say parking or post offices nearby it wont use offline maps and the locking issue occurs

[bigJ334]

Yeah

I also have location always ON for Google maps instead of 'when app open only'

Could be some network connection settings or Google maps issues.

I am presuming all your apps are upto to date from both Google and Samsung store

[bigJ334]

Yep, I have the same location permission setting too. All apps are up to date

What about mobile roaming.

Mine are ON along with 2g.

See if it helps the cause.

Reach out to Google Maps so development team and your network

I have 2g turned on. Roaming is turned off as I am using domestic networks and I'm not in a roaming area
